ABSTRACT
BACKGROUND:
Central venous catheters are widely used in clinical practice, and the incidence of central venous catheter occlusion is between 25â¯% and 38â¯%. The turbulence caused by the pulsatile flushing technique is harmful to the vascular endothelium and may lead to phlebitis. The low-speed continuous infusion catheter technique is a new type of continuous infusion that ensures that the catheter is always in a keep-vein-open state by continuous low-speed flushing; hence, avoiding the problem of catheter occlusion.OBJECTIVE:
To investigate the effectiveness of the low-speed continuous infusion catheter technique and the routine care of double-lumen central venous catheters.DESIGN:
This was a prospective, randomized, controlled, open-label trial.SETTING:
Patients were recruited from 14 medical institutions in China between February and June 2023.PARTICIPANTS:
In total, 251 patients were recruited, with 125 in the intervention group and 126 in the control group.METHODS:
Patients who used double-lumen central venous catheters for infusion treatment were selected, and those who met the sampling criteria were randomly divided into intervention and control groups using the random envelope method. The intervention group used the low-speed continuous infusion catheter technique to maintain catheter patency, whereas the control group used routine care with a trial period of 7â¯days. The primary outcome was the occlusion rate. The secondary outcomes included nursing satisfaction and complication rates of the two groups.RESULTS:
After 7â¯days, the rate of catheter occlusion was 28.0â¯% (35/125, 95â¯% confidence interval (CI)0.203, 0.367) in the intervention group and 53.97â¯% (68/126, 95â¯% CI 0.449-0.629) in the control group, with a statistically significant difference (χ2â¯=â¯17.488, pâ¯<â¯0.001); at 3â¯days of intervention, the rate of catheter blockage was 8.0â¯% (10/125, 95â¯% CI 0.039-0.142) in the intervention group and 23.8â¯% (30/126, 0.167-0.322) in the control group, with a statistically significant difference (χ2â¯=â¯11.707, pâ¯<â¯0.001). Nurse satisfaction was significantly higher in the intervention group (115/125, 92.0â¯%, 95â¯% CI 0.858-0.961) than in the control group (104/126, 82.54â¯%, 95â¯% CI 0.748-0.887) (χ2â¯=â¯5.049, pâ¯=â¯0.025). There were no statistically significant complication rates in either group (pâ¯=â¯0.622).CONCLUSION:
The low-speed continuous infusion catheter technique helps maintain catheter patency, improves nurse satisfaction, and provides a high level of safety.
